The Future of Solar modelling: requirements for a new generation of solar models
Gael Buldgen, Gloria. Canocchi, Arthur. Le Saux +22
Helioseismology and solar modelling have enjoyed a golden era thanks to decades-long surveys from ground-based networks such as for example GONG, BiSON, IRIS and the SOHO and SDO s…
Entropy proxy inversions as tracers of the evolution of physical conditions at the base of the solar convective envelope
G. Buldgen, A. Noels, V. A. Baturin +4
The Sun is an important calibrator for the theory of stellar structure and evolution. However, the accuracy of our solar evolution models is tightly linked to the physical ingredie…
Helioseismic inference of the solar radiative opacity
Gaël Buldgen, Jean-Christophe Pain, Philippe Cossé +18
The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current deb…
Hydrogen Ionization Inside the Sun
V. A. Baturin, S. V. Ayukov, A. V. Oreshina +4
Hydrogen is the main chemical component of the solar plasma, and H-ionization determines basic properties of the first adiabatic exponent . Hydrogen ionization remarkably diff…
Heavy Elements Abundances Inferred from the First Adiabatic Exponent in the Solar Envelope
V. A. Baturin, A. V. Oreshina, G. Buldgen +5
The first adiabatic exponent profile, noted , computed along adiabatic coordinates is in the focus of our study. Under conditions of almost fully ionized hydrogen and…
Helioseismic determination of the solar metal mass fraction
G. Buldgen, A. Noels, V. A. Baturin +5
Context. The metal mass fraction of the Sun Z is a key constraint in solar modelling, but its value is still under debate. The standard solar chemical composition of the late 2000s…
Ionization of heavy elements and the adiabatic exponent in the solar plasma
V. A. Baturin, A. V. Oreshina, W. Däppen +4
Context. The adiabatic exponent is studied as a thermodynamic quantity in the partially ionized plasma of the solar convection zone. Aims. The aim of this study is to underst…
Interpolation of equation-of-state data
V. A. Baturin, W. Däppen, A. V. Oreshina +2
Aims. We use Hermite splines to interpolate pressure and its derivatives simultaneously, thereby preserving mathematical relations between the derivatives. The method therefore gua…
Helioseismic Measurements in the Solar Envelope Using Group Velocities of Surface Waves
S. V. Vorontsov, V. A. Baturin, S. V. Ayukov +1
At intermediate and high degree , solar p- and f modes can be considered as surface waves. Using variational principle, we derive an integral expression for the group velocities…
